Why would you care whether it is "frowned upon" if it's the best way to
achieve something useful?
So the real question is /what/ you are trying to do and what your options
are.
PS: vars(a) is the non-dunder equivalent of a.__dict__. Both have the same
limitations, like failing with __slots__ and not seeing properties and class
attributes.
